Neuroimaging technology is an important technology used to explore the neural mechanisms of acupuncture analgesia. In this study, we extracted original studies published in Chinese and English focusing on the use of neuroimaging technology to explore the mechanisms of acupuncture analgesia from PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, Web of Science, and CNKI databases from January 1999 to August 2020. The extracted data were statistically analyzed in terms of year of publication, country, experimental design, and quality control approaches used, sample size, characteristics of participants, acupuncture operation, and other information. Analysis of the literature revealed that international cooperation promotes scientific research. Flexible experimental design can better explain the mechanism of acupuncture analgesia. Reasonable sample size, strict participant inclusion criteria, and standard acupuncture practices are essential for repeatability of conclusions. These findings show that attention should be paid to quality control in future research to improve the reliability of research on acupuncture analgesia.
神经影像学技术是用于探索针刺镇痛神经机制的一项重要技术。在本研究中，我们从PubMed、Cochrane对照试验中心注册库（CENTRAL）、EMBASE、科学引文索引（Web of Science）以及中国知网（CNKI）数据库中提取了1999年1月至2020年8月期间发表的聚焦于运用神经影像学技术探索针刺镇痛机制的中英文原始研究。对提取的数据从发表年份、国家、实验设计、所采用的质量控制方法、样本量、参与者特征、针刺操作及其他信息等方面进行了统计分析。文献分析表明国际合作促进科研。灵活的实验设计能更好地解释针刺镇痛机制。合理的样本量、严格的参与者纳入标准以及规范的针刺操作对结论的可重复性至关重要。这些研究结果表明，未来研究应重视质量控制，以提高针刺镇痛研究的可靠性。
